Abstract
Phytochemical constituents of the root extract of Aloe ferox were estimated using standard quantitative analysis. The extract contained phenols, flavonoids, flavonols, tannins alkaloids and saponins in different proportions; with more of phenols and saponins. Allelopathic effect of the aqueous root extract of the plant on tomato was also investigated. The extract reduced the germination of the tomato seeds. However, root and shoot elongations of the tomato seedlings were significantly inhibited by the extract, with the percentage inhibition increasing as the concentration of the extract increased. The observed allelopathic activity of the root extract of A. ferox on the seed germination and seedling growth of tomato was attributed to the presence of the allelopathic phytochemicals in A. ferox roots.
